FIELD OF THE INVENTION

The present invention relates generally to media content experience and more specifically to a system and method for providing an immersive surround environment for enhanced content experience.

BACKGROUND OF THE INVENTION

Rendering of media (image/audio/speech/video/audio-video) content on any system including television, cinema halls, personal computer is generally based on a single media stream. A viewer has limited options as far as content is concerned. The role of the viewer in conventional content rendering devices is quite passive. The user can only increase or decrease the volume, change the brightness or contrast level of the rendering device and can record or playback content among other features that are available on content rendering devices. However, if a user wants to immerse himself in the scene he has to watch the content with great interest and involvement which is not possible in all situations.

To overcome the abovementioned disadvantages, contents have been encoded with surround sound and vision parameters wherein the user is able to feel the sense of direction and is able to feel realism because of sound, lighting effects and three dimensional displays. However, experience of feeling the situation or content is still not achieved by the abovementioned solutions.

In light of the abovementioned disadvantages, there is a need for a system and method for providing an immersive enhanced content experience to the users. Further, there is a need to employ environmental parameters in synchronization with the media stream. In addition, there is a need to insert environmental parameters in the stream during encoding for better depiction of content and to generate real effects while rendering. Furthermore, there is a need to encode environmental parameters separately with frame sync and/or other stream elements synchronization information and play it back along with media stream with the help of a device or play it along with media content.

The disclosure is provided in order to enable a person having ordinary skill in the art to practice the invention. Exemplary embodiments herein are provided only for illustrative purposes and various modifications will be readily apparent to persons skilled in the art. The general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the invention. The terminology and phraseology used herein is for the purpose of describing exemplary embodiments and should not be considered limiting. Thus, the present invention is to be accorded the widest scope encompassing numerous alternatives, modifications and equivalents consistent with the principles and features disclosed herein. For purpose of clarity, details relating to technical material that is known in the technical fields related to the invention have been briefly described or omitted so as not to unnecessarily obscure the present invention.

The present invention would now be discussed in context of embodiments as illustrated in the accompanying drawings.

FIG. 1 illustrates a system 100 for providing an immersive surround environment for enhanced content experience, in accordance with an embodiment of the present invention. In various embodiments of the present invention, enhanced content experience includes viewing, listening, feeling, touching or any other sensory experience related to the rendered content. The system of the invention uses environmental parameters to extend existing concepts of ‘surround’ sound and vision to provide an immersive experience to users. The vicinity where audio-visual equipment is located may be considered as an extended environment of scene depicted in audio-visual content. The extended environment is used to provide environmental experience corresponding to environment depicted in scenes of audio-visual content. In an embodiment of the present invention, environmental parameters are encoded in a media stream and thereafter the media stream is decoded to extract the media data and environmental parameters. In various embodiments of the present invention, the media stream includes, but is not limited to, an image stream, an audio stream, a speech stream, a video stream and an audio-video stream. The environmental parameters are then used to activate systems that control environmental conditions in vicinity of the audio-visual equipment. As shown in the figure, the system 100 includes a media decoder 102, a content analyzer 104, a stream and environmental parameter sync module 106, a standard player/decoder 108, an environmental parameter based decoder 110, a media and environmental parameter splitter 112 and an environmental effect playback system 114. In an embodiment of the present invention, an encoded video stream is fed into the decoder 102. The encoded media stream may be an image stream such as JPEG, BMP, GIF, TIFF, PNG, JPEG2000, an audio/speech stream such as WAV, MPEG, G.711, G.723, AC3, AAC, WMA, a video stream compressed and encoded in accordance with standard video specifications such as MPEG-2, MPEG-4, AVS, VC-1, Dirac, H.264, an audio-video file format such as AVI, 3GP, WMV, DivX, MPEG-4, AVCHD etc. or even a raw uncompressed stream. In an embodiment of the present invention, the encoded stream may be a still image. The media decoder 102 decodes the media stream to extract raw media data. The content analyzer 104 extracts environmental parameters such as temperature, ambient light, humidity, wind velocity, thunders (such as ice, snow, fore, thunder, wind etc.) etc. from the raw video stream. In an embodiment of the present invention, the environmental parameters are extracted from various factors such as color layout, structure, shape, region, texture, location, face and motion of image/video stream. In another embodiment of the present invention the environmental parameters are extracted from various factors such as color layout, structure, shape, region, texture, location, face, motion from image and video stream, and/or pitch, harmony, tempo, rhythm, loudness, lyrics analyzer of audio/speech stream. In yet another embodiment of the present invention, the environmental parameters are extracted from various factors such as color layout, structure, shape, region, texture, location, face, motion from image and video stream, and pitch, harmony, tempo, rhythm, loudness, lyrics analyzer of audio-video stream.

The extracted environmental parameters are provided to the stream and environmental parameter sync module 106. Further, frame sync and stream elements information is provided by the media decoder 102 to the stream and environmental parameter sync module 106.

The stream and environmental parameter sync module 106 is similar to an audio video synchronizer used for synchronizing the encoded stream with the environmental parameters. In another embodiment of the present invention, instead of using extracted environmental parameters from media stream, environmental parameters are artificially simulated and/or manually extracted and are synchronized with encoded stream by the stream and environmental parameter sync module 106. Synchronization of environmental parameters with encoded stream includes processing of parameters in order to align them with the encoded stream and embed them along with the stream elements of the media stream at appropriate places in a non-intrusive manner such that these extra information can be skipped if the decode or player does not support it.

In an embodiment of the present invention, the encoded stream with embedded environmental parameters is provided to a standard player/decoder 108. The standard decoder 108 decodes the encoded stream, while ignoring environmental parameters. The standard decoder 108 then provides a media output independent of the environmental parameters.

In another embodiment of the present invention, the encoded stream with embedded environmental parameters is provided to the environmental parameter based decoder 110. The environmental parameter based decoder 110 is a specialized decoder configured to understand effect of environmental parameters on the encoded stream. The environmental parameter based decoder 110 decodes the stream including the effects of environmental parameters and outputs a signal to the media and environmental parameter splitter 112. The media and environmental parameter splitter 112 splits the media output from the environmental effects. The media output is provided to audio/visual equipment for rendering the stream. In an embodiment of the present invention, environmental effects from the media and environmental parameter splitter 112 is provided to the environmental effect playback system 114. Output from the environmental effects playback system 114 is presented to one or more output devices that control environmental conditions. (Device 1, Device 2 . . . Device n) In an embodiment of the present invention, the output device may be a centralized system adapted to control lighting condition, temperature, humidity, wind etc. in the vicinity of the location of the centralized system. For example, when the scene is that of a chilly full moon night, the centralized system uses the environmental effects output to adjust an air conditioner in order to simulate a cold environment. As a result, a viewer/listener experiences coldness in surrounding environment. Similarly, the centralized system may activate lighting system to simulate white light that may signify moonlight. In another example, if in a particular scene, the actor is walking through Sahara desert, the environmental effects are used to simulate heat so that the viewer feels scorching heat and humidity or the song is that of a rain, sprinklers can be turned on. The system 100 controls the environment so that the viewer is fully involved in the audio-visual scene, experiences what is going on and becomes part of content happening. In an embodiment of the present invention, the one or more output devices connected to the environmental effects output may not be configured to reproduce one or more environmental effects provided by the environmental effects playback system. In this case, devices configured to reproduce environmental effects are activated according to their respective environmental parameters and unusable environmental parameters are ignored.

The media decoder 202 decodes the encoded media stream to extract raw media data.

FIG. 8 illustrates embedding environmental parameters at different levels within a stream. In various embodiments of the present invention, environmental parameters can be embedded at six levels within a video stream with respect to granularity of the stream. The level depiction is generic in nature and covers all video standard structures, however, this varies for video standard to standard. At level 1, environmental parameters can be added globally in the stream 802. Global environment information may be added in a scenario where the environmental conditions related to scenes of a video capture remain constant for the entire stream 802. For example, in case, a video stream is video data related to a single scene shoot in a particular cold place, such as Antarctica, the environmental conditions are constant for the entire video stream.

At level 2, environmental parameters can be added for ‘Group of Pictures’ 804 for the video stream. A ‘Group of Pictures’ is associated with a particular scene in a video stream. In an example, since environmental conditions for a particular scene remain same, common environmental parameters can be embedded for the ‘Group of Pictures’ which override global information. For example, night scene followed by a morning scene. Further, at level 3, environmental parameters can be embedded for a frame which overrides both global and ‘Group of Pictures’ level information. At level 4, each frame 808 is divided into a region of interest or non-region of interest. Each region thus specified is considered as a slice and environmental parameters for each slice may be different depending upon situation. In an exemplary embodiment, various inanimate objects located at different slices within a frame may require different levels of illumination depending upon the type of object. In an example, the type of illumination required for a metal ball may be different than that required for a chalk. In an embodiment of the present invention, environmental information specific to a slice overrides information at global level, ‘Group of Pictures’ level, and at frame level.

At level 5, each frame may be divided into macroblocks. Each macroblock 810 is a region of 16×16 pixels for a luminance and 8×8 for chrominance channels. Environmental information which is embedded specific to a macroblock overrides information embedded at levels 1-4.

Finally, at level 6, each macroblock comprises one or more blocks 812. Each block 812 comprises one or more pixels. In an exemplary embodiment of the present invention, environmental information is embedded specific to a pixel in order to introduce increased level of granularity in controlling of environmental information in a frame. The environmental information embedded specific to a pixel overrides information embedded at all levels.

FIG. 9 illustrates audio file structure of an audio stream provided as input to media decoder, in accordance with an embodiment of the present invention. As shown in the figure, audio streams 902, 904, 906 and 908 comprise 1-channel, 2-channel, 4-channel and n-channel audio data respectively. The method and system of the present invention is configured to process the audio streams 902, 904, 906 and 908. In various embodiments, the system and method of the present invention may receive the audio streams 902, 904, 906 and 908 that are encoded using various audio compression standards having different encoding mechanism. An audio frame is a set of audio samples that are coincident in time. The sample frame 910 for a 1-channel audio data is a single sample. However, the sample frame 912 for a 2-channel audio data consists of a left-right sample pair having left channel samples interleaved alternately with right channel samples.

The audio stream 906 is a 4-channel audio stream with the frame 914 having two left-right sample pairs or other arrangements.

FIG. 10 illustrates embedding a media stream with environmental parameters, in accordance with an embodiment of the present invention. The encoded stream 1002 is compressed using the H.264 video compression standard. The environmental parameter stream 1004 takes the structure of the encoded stream 1002 such that environmental parameter information can be embedded in a synchronized manner. The environmental parameter stream 1004 uses the same data structure i.e. header is retained and content part of the encoded stream 1002 is ignored. As shown in the figure, the encoded stream 1002 comprises Sequence Parameter Set (SPS), Picture Parameter Set (PPS), slice and other low level identifiers within the slice. In various embodiments of the present invention, the environmental parameter stream 1004 retains the SPS, PPS and slice header information for synchronization and removes the data part. Further, the environmental parameters to be linked or mapped to a specific identifier are embedded to the encoded stream content 1006 i.e. to the SPS, PPS and slice part in order to obtain encoded stream embedded with environmental parameters.

FIG. 11 illustrates encoding a media stream with environmental parameters, in accordance with an embodiment of the present invention. In various embodiments of the present invention, the environmental parameter stream to be encoded separately takes the structure of the encoded stream 1102 with which it has to be synced. However, the environmental parameter structure is generic in nature. The environmental parameter stream 1104 comprises placeholders for image/audio/speech/video/audio-video content similar to audio-video file format container. Examples of placeholders include placeholders for image streams such as JPEG, PNG etc., placeholders for audio/speech streams such as MP3, placeholders for audio streams and audio-video file formats. However, the environmental parameter encoder uses data structure minus the data of that standard encoded stream and rest of the references for other media standards are left empty. As shown in the figure, the encoded stream 1102 comprises Sequence Parameter Set (SPS), Picture Parameter Set (PPS), slice and other low level identifiers within the slice. In various embodiments of the present invention, the environmental parameter stream 1104 retains the SPS, PPS and slice header information for synchronization and removes the data part.
